Drill bit Dedra DED1532, 5 mm, steel, for glass and tile, 1 pc

Dedra DED1532 drill bit, 5 mm diameter, is a steel bit specifically designed for drilling brittle surfaces such as glass and ceramic tile. Supplied as a single piece, it enables precision work when installing fittings, making repairs or creating clean holes in finished surfaces. The bit is intended for use with rotary drills at controlled speeds and with appropriate cooling to reduce the risk of cracking or chipping on delicate materials.

Advantages

The Dedra DED1532 offers a narrow 5 mm cutting profile that helps produce accurate, clean holes in glass and ceramic tile. Its steel construction provides durability for occasional professional or DIY use while the single-piece design simplifies handling and positioning. When used with correct drilling technique—low speed, steady pressure and cooling—this bit minimises damage to brittle surfaces and delivers repeatable results.

Suitable for

• Drilling holes in glass panes for fixtures or fittings
• Creating holes in ceramic wall and floor tiles during bathroom and kitchen installations
• Repair and maintenance tasks requiring precise small-diameter holes in brittle materials

Key specifications

• Diameter: 5 mm
• Material: steel
• Intended materials: glass, ceramic tile
• Quantity in package: 1 piece

How to use

Secure the workpiece and mark the drilling location. Use a rotary drill with adjustable speed, start at low revolutions and apply steady, moderate pressure. For glass and ceramic tile, keep the bit aligned perpendicular to the surface and consider using a piece of masking tape over the mark to reduce wandering. Apply cooling or water to the drill point intermittently to lower temperature and reduce the risk of cracking. After penetrating the surface, reduce pressure and finish the hole at a controlled speed to avoid chipping the exit side.

Usage recommendations

Use personal protective equipment (safety glasses and gloves), clamp or support the workpiece firmly, and test drilling speed on a scrap piece when possible. Maintain low to medium drill speed, keep the bit cooled with water, and avoid excessive lateral force to extend bit life and protect brittle materials.
